LM393 Infrared Velometer optical encoder Speed Sensor Optocoupler Tacho Sensor Slot-type Tacho-generator Counter

1. Working voltage: 3.3--5.5V
2. The use of imported groove coupler sensor, the groove width of 5mm.
3. The sensor slots are blocked, the output high and the light is off; no shelter, output low and lights.
4. Output form: Digital switching output (0 and 1)
5. Using LM393 comparator output, type clean, good waveform, driving ability over 15mA.
6. A fixed bolt hole for easy mounting.

Having a signal output directions. a single-channel signal output. the output valid signal is low. The sensitivity is not adjustable, can be used for parts counting, motor speed, the circuit board output switch.
